Optic nerve sheath diameter (ONSD) The anatomy of the optic nerve sheath : The intraorbital section of the optic nerve extends from the globe‚ where it inserts medially‚ to the optic canal located in the lesser wing of the sphenoid bone. It is encased by a meningeal sheath consisting of dura mater‚ arachnoid mater and pia mater. Cerebrospinal fluid is contained in the trabeculated subarachnoid space and is continuously and slowly filtered. As a result the optic nerve sheath is in direct

That was fast: The influence of light intensity on the growth and development of Wisconsin Fast Plants Introduction It is common knowledge that plants need light to grow and develop. This is done by the conversion of light energy into usable sugars during photosynthesis. Light absorbing molecules‚ known as pigments‚ absorb only specific wavelengths of visible light‚ mostly blue and red wavelengths (1). Whatever wavelength isn’t absorbed is reflected and the reflection is the color of plant we

energy from our hands to the ice and the temperature difference between the two objects. The energy we are familiar with is called heat while temperature is the measure of a degree of heat or coldness of an object. In everyday life‚ heat or cold is commonly used to explain the degree of temperature of an object. An object that is said to be hot means it has a high temperature. Similarly‚ when an object is said to be cold‚ is means it is has a low temperature.  IMAGE GOES HERE Image Source Why

is which type of temperature change will result from heating ice to liquid‚ then boil (steam)? What will happen to the water after the boil? I hypothesise the water heats ice to liquid and then goes to simmer and boil. The independent variable is the hot plate changed to a burner itself. The dependent variable is what we are measuring is the time. The steps in the lab were to first start off with a burner‚ ice and water in a beaker‚ then record time and water temperature. Also‚ some phase

Negative Temperature Coefficient (NTC) thermistors exhibit a decrease in electrical resistance when subjected to an increase in body temperature and Positive Temperature Coefficient (PTC) thermistors exhibit an increase in electrical resistance when subjected to an increase in body temperature. U.S. Sensor produces thermistors capable of operating over the temperature range of -100 ° to over +600 ° Fahrenheit. Because of their

Title: Investigate the breakdown of starch at different temperature AIM This experiment has been done to investigate the action of the enzyme amylase on the breakdown of starch. MATERIALS These were the materials used: four starch/ agar plates‚ a marker pen‚ 1mm graph paper ruler‚ 8mm cork borer‚ forceps and template for cutting holes‚ 1% Amylase‚ water‚ incubator set at 5‚ 20‚ 40 and 60 degree Celsius. METHOD This was the experimental procedure carried out: the materials above were collected

To begin the analysis‚ the properties of the air at the base of the tower were examined. The wet and dry bulb temperatures of the air at the inlet were used to find the humidity‚ humid volume‚ and enthalpy of dry air. For example‚ in the first trial the dry bulb temperature was 22.5⁰C and the wet bulb was 16.5⁰C‚ and the properties found from the psychrometric chart are listed below. H_bottom=0.0095 kg/(kg dry air) V_bottom=0.85 m^3/(kg dry air) h_bottom=47 kg/(kg dry air) Then‚ the cross-sectional

Lab Report: How Temperature affects Reaction Rate Aim: The Aim is to investigate how temperature can affect Reaction Rate. The experiment will be performed by heating equally sized and weighted lime stones with equal amounts and concentration of Hydrochloric acid at different temperatures. The temperatures will be 35˚C and 40˚C. We will measure the reaction rates by observing gas release of the reaction between lime stones and Hydrochloric acid. The amount of gas release at different

insects‚ fish and worm. These animals rely on the outside environment for their body heat as they do not generate heat internally like a mammal or bird. Ectotherms have a variety of adaptations‚ many of them behavioural‚ to regulate their body temperature and keep it within the range in which they can be active; 10-30oC The Tiliqua or more commonly known as the blue-tongue lizard or just Blue tongue is the largest member of the skink family in Australia.
